First, the headline. You don't need modulo arithmetic to wrap the buffer if you use bit ints to hold the head & tail "pointers", and size them so they are perfectly in synch. IE: 4096 stuffed into a 12-bit unsigned int is 0 all by itself, unmolested in any way. Eliminating modulo arithmetic, even for powers of 2, doubles the speed - almost exactly.

10 million iterations of filling and draining a 4096 buffer of any type of data elements takes 52 seconds on my 3rd Gen i7 Dell XPS 8500 using Visual Studio 2010's C++ compiler with default inlining, and 1/8192nd of that to service a datum.

I'd RX rewriting the test loops in main() so they no longer control the flow - which is, and should be, controlled by the return values indicating the buffer is full or empty, and the attendant break; statements. IE: the filler and drainer should be able to bang against each other without corruption or instability. At some point I hope to multi-thread this code, whereupon that behavior will be crucial.

The QUEUE_DESC (queue descriptor) and initialization function forces all buffers in this code to be a power of 2. The above scheme will NOT work otherwise. While on the subject, note that QUEUE_DESC is not hard-coded, it uses a manifest constant (#define BITS_ELE_KNT) for its construction. (I'm assuming a power of 2 is sufficient flexibility here)

To make the buffer size run-time selectable, I tried different approaches (not shown here), and settled on using USHRTs for Head, Tail, EleKnt capable of managing a FIFO buffer[USHRT]. To avoid modulo arithmetic I created a mask to && with Head, Tail, but that mask turns out to be (EleKnt -1), so just use that. Using USHRTS instead of bit ints increased performance ~ 15% on a quiet machine. Intel CPU cores have always been faster than their buses, so on a busy, shared machine, packing your data structures gets you loaded and executing ahead of other, competing threads. Trade-offs.

Note the actual storage for the buffer is allocated on the heap with calloc(), and the pointer is at the base of the struct, so the struct and the pointer have EXACTLY the same address. IE; no offset required to be added to the struct address to tie up registers.

In that same vein, all of the variables attendant with servicing the buffer are physically adjacent to the buffer, bound into the same struct, so the compiler can make beautiful assembly language. You'll have to kill the inline optimization to see any assembly, because otherwise it gets crushed into oblivion.

To support the polymorphism of any data type, I've used memcpy() instead of assignments. If you only need the flexibility to support one random variable type per compile, then this code works perfectly.

For polymorphism, you just need to know the type and it's storage requirement. The DATA_DESC array of descriptors provides a way to keep track of each datum that gets put in QUEUE_DESC.pBuffer so it can be retrieved properly. I'd just allocate enough pBuffer memory to hold all of the elements of the largest data type, but keep track of how much of that storage a given datum is actually using in DATA_DESC.dBytes. The alternative is to reinvent a heap manager.

This means QUEUE_DESC's UCHAR *pBuffer would have a parallel companion array to keep track of data type, and size, while a datum's storage location in pBuffer would remain just as it is now. The new member would be something like DATA_DESC *pDataDesc, or, perhaps, DATA_DESC DataDesc[2^BITS_ELE_KNT] if you can find a way to beat your compiler into submission with such a forward reference. Calloc() is always more flexible in these situations.

You'd still memcpy() in Q_Put(),Q_Get, but the number of bytes actually copied would be determined by DATA_DESC.dBytes, not QUEUE_DESC.EleBytes. The elements are potentially all of different types/sizes for any given put or get.

I believe this code satisfies the speed and buffer size requirements, and can be made to satisfy the requirement for 6 different data types. I've left the many test fixtures in, in the form of printf() statements, so you can satisfy yourself (or not) that the code works properly. The random number generator demonstrates that the code works for any random head/tail combo.

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

to_date() returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:

select * 
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')

You probably want to create an index on trunc(es_date) if that is something you are doing on a regular basis.

The literal '27-APR-12' can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date() with a proper format mask (or an ANSI literal: date '2012-04-27')

Although you did right in using to_date() and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'.

With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy') when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy' or 'yyyy-mm-dd'

Short version for easy use:

SELECT * 
FROM [TableName] t
WHERE t.[DateColumnName] >= DATEADD(month, -1, GETDATE())

DATEADD and GETDATE are available in SQL Server starting with 2008 version. MSDN documentation: GETDATE and DATEADD.

First Way:

• Create a new AMI of the instance
• Launch it

Alternative Way:

• Make a snapshot of the disk
• Launch a large EBS instance with the same AMI type (please note that at this point the disk will contain the data that was present when this AMI was created, not your latest changes)
• Once is fully booted, stop the new instance
• Detach the root volume from the stopped instance
• Create a virtual disk from the snapshot created before in the same availability zone of the new instance
• Attach the root volume to /dev/sda1
• Start the new instance again

Seems to be a common feature of the prevalent asymmetric cryptography; the generation of public/private keys involves generating the private key, which contains the key pair:

openssl genrsa -out mykey.pem 1024

Then publish the public key:

openssl rsa -in mykey.pem -pubout > mykey.pub

or

openssl rsa -in mykey.pem -pubout -out mykey.pub

DSA & EC crypto keys have same feature: eg.

openssl genpkey -algorithm ed25519 -out pvt.pem

Then

openssl pkey -in pvt.pem -pubout > public.pem

or

openssl ec -in ecprivkey.pem -pubout -out ecpubkey.pem

The public component is involved in decryption, and keeping it as part of the private key makes decryption faster; it can be removed from the private key and calculated when needed (for decryption), as an alternative or complement to encrypting or protecting the private key with a password/key/phrase. eg.

openssl pkey -in key.pem -des3 -out keyout.pem

or

openssl ec -aes-128-cbc -in pk8file.pem -out tradfile.pem

You can replace the first argument "aes-128-cbc" with any other valid openssl cipher name

While the marked answer is correct there is a way of achieving this without exceptions. The service is returning Optional<T> of the searched object and this is mapped to HttpStatus.OK if found and to 404 if empty.

@Controller
public class SomeController {

    @RequestMapping.....
    public ResponseEntity<Object> handleCall() {
        return  service.find(param).map(result -> new ResponseEntity<>(result, HttpStatus.OK))
                .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }
}

@Service
public class Service{

    public Optional<Object> find(String param){
        if(!found()){
            return Optional.empty();
        }
        ...
        return Optional.of(data); 
    }

You might be able to use IN, if you don't actually need wildcards.

SELECT * from table WHERE column IN ('AAA', 'BBB', 'CCC')

better solution is to use pool - ill handle this for you.

const pool = mysql.createPool({_x000D_
  host: 'localhost',_x000D_
  user: '--',_x000D_
  database: '---',_x000D_
  password: '----'_x000D_
});_x000D_
_x000D_
// ... later_x000D_
pool.query('select 1 + 1', (err, rows) => { /* */ });

The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever.

Database Side (SQL server) I have stored procedure named getNextNmber

My program seems to suffer from linear access to dictionaries, its run-time grows exponentially even though the algorithm is quadratic.

I use a dictionary to memoize values. That seems to be a bottleneck.

This is evidence of a bug in your memoization method.

import numpy as np
a = np.array([[1,3,4],[1,2,3],[1,2,1]])
b = np.array([10,20,30])
c = np.hstack((a, np.atleast_2d(b).T))

returns c:

array([[ 1,  3,  4, 10],
       [ 1,  2,  3, 20],
       [ 1,  2,  1, 30]])

You could also use:

List<int> codes = new List<int>();

codes.add(1);
codes.add(2);

var foo = from codeData in channel.AsQueryable<CodeData>()
          where codes.Any(code => codeData.CodeID.Equals(code))
          select codeData;

Say you had some URL that gave you JSON data like:

{'field': 'value'}

...and you had a similar URL except it used JSONP, to which you passed the callback function name 'myCallback' (usually done by giving it a query parameter called 'callback', e.g. http://example.com/dataSource?callback=myCallback). Then it would return:

myCallback({'field':'value'})

...which is not just an object, but is actually code that can be executed. So if you define a function elsewhere in your page called myFunction and execute this script, it will be called with the data from the URL.

The cool thing about this is: you can create a script tag and use your URL (complete with callback parameter) as the src attribute, and the browser will run it. That means you can get around the 'same-origin' security policy (because browsers allow you to run script tags from sources other than the domain of the page).

This is what jQuery does when you make an ajax request (using .ajax with 'jsonp' as the value for the dataType property). E.g.

$.ajax({
  url: 'http://example.com/datasource',
  dataType: 'jsonp',
  success: function(data) {
    // your code to handle data here
  }
});

Here, jQuery takes care of the callback function name and query parameter - making the API identical to other ajax calls. But unlike other types of ajax requests, as mentioned, you're not restricted to getting data from the same origin as your page.

In Visual Basic, you can call a parameterless method without the braces (()). In C#, they're mandatory. So you should write:

String guid = System.Guid.NewGuid().ToString();

Without the braces, you're assigning the method itself (instead of its result) to the variable guid, and obviously the method cannot be converted to a String, hence the error.

Adding my two cents, based on a performance issue I observed.

If simple queries are getting parellelized unnecessarily, it can bring more problems than solving one. However, before adding MAXDOP into the query as "knee-jerk" fix, there are some server settings to check.

In Jeremiah Peschka - Five SQL Server Settings to Change, MAXDOP and "COST THRESHOLD FOR PARALLELISM" (CTFP) are mentioned as important settings to check.

Note: Paul White mentioned max server memory aslo as a setting to check, in a response to Performance problem after migration from SQL Server 2005 to 2012. A good kb article to read is Using large amounts of memory can result in an inefficient plan in SQL Server

Jonathan Kehayias - Tuning ‘cost threshold for parallelism’ from the Plan Cache helps to find out good value for CTFP.

Why is cost threshold for parallelism ignored?

Aaron Bertrand - Six reasons you should be nervous about parallelism has a discussion about some scenario where MAXDOP is the solution.

Parallelism-Inhibiting Components are mentioned in Paul White - Forcing a Parallel Query Execution Plan

I found the Popen above to be the best solution. It's quick and dirty and it works For python 2.6 on Unix machine i used the following

def GetLastNLines(self, n, fileName):
    """
    Name:           Get LastNLines
    Description:        Gets last n lines using Unix tail
    Output:         returns last n lines of a file
    Keyword argument:
    n -- number of last lines to return
    filename -- Name of the file you need to tail into
    """
    p = subprocess.Popen(['tail','-n',str(n),self.__fileName], stdout=subprocess.PIPE)
    soutput, sinput = p.communicate()
    return soutput

soutput will have will contain last n lines of the code. to iterate through soutput line by line do:

for line in GetLastNLines(50,'myfile.log').split('\n'):
    print line

1. You need to find a repo that offers a GD lib matching your current php version. I've had great success using Remi Collet's repo for this purpose. In fact, I used it yesterday to update my php install to the latest 5.4.0RC6 version on my CentOS6 box.
2. Once you've setup the repo it's a simple matter of running sudo yum install php-gd
3. Of course, the usual things apply: make sure you restart apache after installing, etc.

The C++ build system (compiler) knows no difference, so it's all one of conventions.

The convention is that .h files are declarations, and .cpp files are definitions.

That's why .h files are #included -- we include the declarations.

Here's how I would do this:

class ClassPropertyDescriptor(object):

    def __init__(self, fget, fset=None):
        self.fget = fget
        self.fset = fset

    def __get__(self, obj, klass=None):
        if klass is None:
            klass = type(obj)
        return self.fget.__get__(obj, klass)()

    def __set__(self, obj, value):
        if not self.fset:
            raise AttributeError("can't set attribute")
        type_ = type(obj)
        return self.fset.__get__(obj, type_)(value)

    def setter(self, func):
        if not isinstance(func, (classmethod, staticmethod)):
            func = classmethod(func)
        self.fset = func
        return self

def classproperty(func):
    if not isinstance(func, (classmethod, staticmethod)):
        func = classmethod(func)

    return ClassPropertyDescriptor(func)


class Bar(object):

    _bar = 1

    @classproperty
    def bar(cls):
        return cls._bar

    @bar.setter
    def bar(cls, value):
        cls._bar = value


# test instance instantiation
foo = Bar()
assert foo.bar == 1

baz = Bar()
assert baz.bar == 1

# test static variable
baz.bar = 5
assert foo.bar == 5

# test setting variable on the class
Bar.bar = 50
assert baz.bar == 50
assert foo.bar == 50

The setter didn't work at the time we call Bar.bar, because we are calling TypeOfBar.bar.__set__, which is not Bar.bar.__set__.

Adding a metaclass definition solves this:

class ClassPropertyMetaClass(type):
    def __setattr__(self, key, value):
        if key in self.__dict__:
            obj = self.__dict__.get(key)
        if obj and type(obj) is ClassPropertyDescriptor:
            return obj.__set__(self, value)

        return super(ClassPropertyMetaClass, self).__setattr__(key, value)

# and update class define:
#     class Bar(object):
#        __metaclass__ = ClassPropertyMetaClass
#        _bar = 1

# and update ClassPropertyDescriptor.__set__
#    def __set__(self, obj, value):
#       if not self.fset:
#           raise AttributeError("can't set attribute")
#       if inspect.isclass(obj):
#           type_ = obj
#           obj = None
#       else:
#           type_ = type(obj)
#       return self.fset.__get__(obj, type_)(value)

Now all will be fine.

If is ok for you to index the array you can do this:

<form>
    <input type="text" class="form-control" placeholder="Titel" name="levels[0][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[0][build_time]">

    <input type="text" class="form-control" placeholder="Titel" name="levels[1][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[1][build_time]">

    <input type="text" class="form-control" placeholder="Titel" name="levels[2][level]">
    <input type="text" class="form-control" placeholder="Titel" name="levels[2][build_time]">
</form>

... to achieve that:

[levels] => Array ( 
  [0] => Array ( 
    [level] => 1 
    [build_time] => 2 
  ) 
  [1] => Array ( 
    [level] => 234 
   [build_time] => 456 
  )
  [2] => Array ( 
    [level] => 111
    [build_time] => 222 
  )
) 

But if you remove one pair of inputs (dynamically, I suppose) from the middle of the form then you'll get holes in your array, unless you update the input names...

As others have suggested, the best way to do this is to use a join instead of variable assignment. Re-writing your query to use a join (and using the explicit join syntax instead of the implicit join, which was also suggested--and is the best practice), you would get something like this:

select  
  OrderDetails.Sku,
  OrderDetails.mf_item_number,
  OrderDetails.Qty,
  OrderDetails.Price,
  Supplier.SupplierId, 
  Supplier.SupplierName,
  Supplier.DropShipFees, 
  Supplier_Item.Price as cost
from 
  OrderDetails
join Supplier on OrderDetails.Mfr_ID = Supplier.SupplierId
join Group_Master on Group_Master.Sku = OrderDetails.Sku 
join Supplier_Item on 
  Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID 
where 
  invoiceid='339740' 

Open your page in Firefox and get the HTTPFox addon. It will tell you all that you need.

Found this on archivist.incuito:

http://archivist.incutio.com/viewlist/css-discuss/76444

When you first request a page, your browser sends a GET request to the server, which returns the HTML to the browser. The browser then starts parsing the page (possibly before all of it has been returned).

When it finds a reference to an external entity such as a CSS file, an image file, a script file, a Flash file, or anything else external to the page (either on the same server/domain or not), it prepares to make a further GET request for that resource.

However the HTTP standard specifies that the browser should not make more than two concurrent requests to the same domain. So it puts each request to a particular domain in a queue, and as each entity is returned it starts the next one in the queue for that domain.

The time it takes for an entity to be returned depends on its size, the load the server is currently experiencing, and the activity of every single machine between the machine running the browser and the server. The list of these machines can in principle be different for every request, to the extent that one image might travel from the USA to me in the UK over the Atlantic, while another from the same server comes out via the Pacific, Asia and Europe, which takes longer. So you might get a sequence like the following, where a page has (in this order) references to three script files, and five image files, all of differing sizes:

1. GET script1 and script2; queue request for script3 and images1-5.
2. script2 arrives (it's smaller than script1): GET script3, queue images1-5.
3. script1 arrives; GET image1, queue images2-5.
4. image1 arrives, GET image2, queue images3-5.
5. script3 fails to arrive due to a network problem - GET script3 again (automatic retry).
6. image2 arrives, script3 still not here; GET image3, queue images4-5.
7. image 3 arrives; GET image4, queue image5, script3 still on the way.
8. image4 arrives, GET image5;
9. image5 arrives.
10. script3 arrives.

In short: any old order, depending on what the server is doing, what the rest of the Internet is doing, and whether or not anything has errors and has to be re-fetched. This may seem like a weird way of doing things, but it would quite literally be impossible for the Internet (not just the WWW) to work with any degree of reliability if it wasn't done this way.

Also, the browser's internal queue might not fetch entities in the order they appear in the page - it's not required to by any standard.

(Oh, and don't forget caching, both in the browser and in caching proxies used by ISPs to ease the load on the network.)

This worked for me:

npm cache clean --force 

Replace the startsWith function with:

yourString.indexOf(searchString, position) // where position can be set to 0

This will support all browsers including IE

Position can be set to 0 for string matching from the start meaning 0th position.

Assign a value when declaring the variable.

DECLARE @result VARCHAR(1000) ='';

SELECT @result = CAST(StudentId AS VARCHAR) + ',' FROM Student WHERE condition = xyz

It's because the name column on the bar table does not have the UNIQUE constraint.

So imagine you have 2 rows on the bar table that contain the name 'ams' and you insert a row on baz with 'ams' on bar_fk, which row on bar would it be referring since there are two rows matching?

You can use the _getexif() protected method of a PIL Image.

import PIL.Image
img = PIL.Image.open('img.jpg')
exif_data = img._getexif()

This should give you a dictionary indexed by EXIF numeric tags. If you want the dictionary indexed by the actual EXIF tag name strings, try something like:

import PIL.ExifTags
exif = {
    PIL.ExifTags.TAGS[k]: v
    for k, v in img._getexif().items()
    if k in PIL.ExifTags.TAGS
}

We can update GTF answer to update timestamps easily

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);

Coder::insert($data);

Update: to simplify the date we can use carbon as @Pedro Moreira suggested

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'modified_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'modified_at'=> $now
       ),
    //...
);

Coder::insert($data);

UPDATE2: for laravel 5 , use updated_at instead of modified_at

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'updated_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'updated_at'=> $now
       ),
    //...
);

Coder::insert($data);

Use document.location.href to change the page location, place it in the function on a successful ajax run.

A generic answer that may or not apply to this specific case:

As the error message hint at, aclocal-1.15 should only be required if you modified files that were used to generate aclocal.m4

If you don't modify any of those files (including configure.ac) then you should not need to have aclocal-1.15.

In my case, the problem was not that any of those files was modified but somehow the timestamp on configure.ac was 6 minutes later compared to aclocal.m4.

I haven't figured out why, but a clean clone of my git repo solved the issue for me. Maybe something linked to git and how it created files in the first place.

Rather than rerunning autoconf and friends, I would just try to get a clean clone and try again.

It's also possible that somebody committed a change to configure.ac but didn't regenerate the aclocal.m4, in which case you indeed have to rerun automake and friends.

On OSX 10.11, you can sudo nano /etc/paths and add the path(s) you want here, one per line. Way simpler than figuring which of ~/.bashrc, /etc/profile, '~/.bash_profile` etc... you should add to. Besides, why export and append $PATH to itself when you can just go and modify PATH directly...?

As noted by Riedsio, the session variables do not change after connecting unless you specifically set them; setting the global variable only changes the session value of your next connection.

For example, if you have 100 connections and you lower the global wait_timeout then it will not affect the existing connections, only new ones after the variable was changed.

Specifically for the wait_timeout variable though, there is a twist. If you are using the mysql client in the interactive mode, or the connector with CLIENT_INTERACTIVE set via mysql_real_connect() then you will see the interactive_timeout set for @@session.wait_timeout

Here you can see this demonstrated:

> ./bin/mysql -Bsse 'select @@session.wait_timeout, @@session.interactive_timeout, @@global.wait_timeout, @@global.interactive_timeout' 
70      60      70      60

> ./bin/mysql -Bsse 'select @@wait_timeout'                                                                                                 
70

> ./bin/mysql

Here, process="userGroupSetupForm" atrribute is mandatory for Ajax call. actionListener is calling a method from @ViewScope Bean. Also updating growl message, Datatable: userGroupList and Form: userGroupSetupForm.

If by "checked out" you mean people who have cloned your project, then no it is not possible. You don't even need to be a GitHub user to clone a repository, so it would be infeasible to track this.

I don't know if the following tool is exatly what you need. But I like to use, for specific files, some online tool. This way I can use it regardless of the operational system. Here is a example: diffchecker.com

But for my needs, I guess the best tool to track changes and logs of my project's files is GIT. If you work in a team, you can have some repo online in a server of yours, or use it with Bitbucket or Github.

Hope it helps somebody.

Another important issue that I faced which resulted in the same error was:

_values = pd.read_csv("C:\Users\Mujeeb\Desktop\file.xlxs")

^This line resulted in the same error because I am reading an excel file using read_csv() method. Use read_excel() for reading .xlxs

Try this. For example: You should use UINavigationController as the initial view controller. Then, you can set any view controller as root from the storyboard.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let navigationController = storyboard.instantiateInitialViewController() as UINavigationController
    let rootViewController = storyboard.instantiateViewControllerWithIdentifier("VC") as UIViewController
    navigationController.viewControllers = [rootViewController]
    self.window?.rootViewController = navigationController
    return true
}

See my storyboard screen.

Add an extension method.

public static string RemoveLast(this string text, string character)
{
    if(text.Length < 1) return text;
    return text.Remove(text.ToString().LastIndexOf(character), character.Length);
}

then use:

yourString.RemoveLast(",");

The short answer, or TL;DR

Basically, eval is used to evaluate a single dynamically generated Python expression, and exec is used to execute dynamically generated Python code only for its side effects.

eval and exec have these two differences:

1. eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.

   An expression in Python is whatever you can have as the value in a variable assignment:

   a_variable = (anything you can put within these parentheses is an expression)
   

2. eval returns the value of the given expression, whereas exec ignores the return value from its code, and always returns None (in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).

In versions 1.0 - 2.7, exec was a statement, because CPython needed to produce a different kind of code object for functions that used exec for its side effects inside the function.

In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used.

Thus basically:

>>> a = 5
>>> eval('37 + a')   # it is an expression
42
>>> exec('37 + a')   # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47')   # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47')  # you cannot evaluate a statement
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    a = 47
      ^
SyntaxError: invalid syntax

The compile in 'exec' mode compiles any number of statements into a bytecode that implicitly always returns None, whereas in 'eval' mode it compiles a single expression into bytecode that returns the value of that expression.

>>> eval(compile('42', '<string>', 'exec'))  # code returns None
>>> eval(compile('42', '<string>', 'eval'))  # code returns 42
42
>>> exec(compile('42', '<string>', 'eval'))  # code returns 42,
>>>                                          # but ignored by exec

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval') This is where the difference really comes from.

If a code object (which contains Python bytecode) is passed to exec or eval, they behave identically, excepting for the fact that exec ignores the return value, still returning None always. So it is possible use eval to execute something that has statements, if you just compiled it into bytecode before instead of passing it as a string:

>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>

works without problems, even though the compiled code contains statements. It still returns None, because that is the return value of the code object returned from compile.

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

The longer answer, a.k.a the gory details

exec and eval

The exec function (which was a statement in Python 2) is used for executing a dynamically created statement or program:

>>> program = '''
for i in range(3):
    print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>> 

The eval function does the same for a single expression, and returns the value of the expression:

>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84

exec and eval both accept the program/expression to be run either as a str, unicode or bytes object containing source code, or as a code object which contains Python bytecode.

If a str/unicode/bytes containing source code was passed to exec, it behaves equivalently to:

exec(compile(source, '<string>', 'exec'))

and eval similarly behaves equivalent to:

eval(compile(source, '<string>', 'eval'))

Since all expressions can be used as statements in Python (these are called the Expr nodes in the Python abstract grammar; the opposite is not true), you can always use exec if you do not need the return value. That is to say, you can use either eval('my_func(42)') or exec('my_func(42)'), the difference being that eval returns the value returned by my_func, and exec discards it:

>>> def my_func(arg):
...     print("Called with %d" % arg)
...     return arg * 2
...

Of the 2, only exec accepts source code that contains statements, like def, for, while, import, or class, the assignment statement (a.k.a a = 42), or entire programs:

SyntaxError: invalid syntax

Both exec and eval accept 2 additional positional arguments - globals and locals - which are the global and local variable scopes that the code sees. These default to the globals() and locals() within the scope that called exec or eval, but any dictionary can be used for globals and any mapping for locals (including dict of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the executed code creates:

>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}

(If you display the value of the entire g, it would be much longer, because exec and eval add the built-ins module as __builtins__ to the globals automatically if it is missing).

In Python 2, the official syntax for the exec statement is actually exec code in globals, locals, as in

>>> exec 'global a; a, b = 123, 42' in g, l

However the alternate syntax exec(code, globals, locals) has always been accepted too (see below).

compile

The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1) built-in can be used to speed up repeated invocations of the same code with exec or eval by compiling the source into a code object beforehand. The mode parameter controls the kind of code fragment the compile function accepts and the kind of bytecode it produces. The choices are 'eval', 'exec' and 'single':

• 'eval' mode expects a single expression, and will produce bytecode that when run will return the value of that expression:

  >>> dis.dis(compile('a + b', '<string>', 'eval'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 RETURN_VALUE
  

• 'exec' accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None:

  >>> dis.dis(compile('a + b', '<string>', 'exec'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 POP_TOP                             <- discard result
                8 LOAD_CONST               0 (None)   <- load None on stack
               11 RETURN_VALUE                        <- return top of stack
  

• 'single' is a limited form of 'exec' which accepts a source code containing a single statement (or multiple statements separated by ;) if the last statement is an expression statement, the resulting bytecode also prints the repr of the value of that expression to the standard output(!).

  An if-elif-else chain, a loop with else, and try with its except, else and finally blocks is considered a single statement.

  A source fragment containing 2 top-level statements is an error for the 'single', except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:

  In Python 2.7.8:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  >>> a
  5
  

  And in Python 3.4.2:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 1
      a = 5
          ^
  SyntaxError: multiple statements found while compiling a single statement
  

  This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval the resulting code.

Thus greatest distinction of exec and eval actually comes from the compile function and its modes.

In addition to compiling source code to bytecode, compile supports compiling abstract syntax trees (parse trees of Python code) into code objects; and source code into abstract syntax trees (the ast.parse is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.

While eval only allows you to evaluate a string that contains a single expression, you can eval a whole statement, or even a whole module that has been compiled into bytecode; that is, with Python 2, print is a statement, and cannot be evalled directly:

>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print("Python is cool")
      ^
SyntaxError: invalid syntax

compile it with 'exec' mode into a code object and you can eval it; the eval function will return None.

>>> code = compile('for i in range(3): print("Python is cool")',
                   'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool

If one looks into eval and exec source code in CPython 3, this is very evident; they both call PyEval_EvalCode with same arguments, the only difference being that exec explicitly returns None.

Syntax differences of exec between Python 2 and Python 3

One of the major differences in Python 2 is that exec is a statement and eval is a built-in function (both are built-in functions in Python 3). It is a well-known fact that the official syntax of exec in Python 2 is exec code [in globals[, locals]].

Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec statement in CPython 2 can be also used with syntax that looks exactly like the exec function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals) built-in function! And that built-in function was replaced with exec statement somewhere before Python 1.0 release.

Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code was a tuple of length 2 or 3, and globals and locals were not passed into the exec statement otherwise, the code would be interpreted as if the 2nd and 3rd element of the tuple were the globals and locals respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:

The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals. The tuple form of exec provides compatibility with Python 3, where exec is a function rather than a statement.

Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.

Thus while exec is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,

>>> exec("print(a)", globals(), {'a': 42})
42

has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).

What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec into a variable:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
  File "<stdin>", line 1
    a = exec('print(42)')
           ^
SyntaxError: invalid syntax

(which wouldn't be useful in Python 3 either, as exec always returns None), or pass a reference to exec:

>>> call_later(exec, 'print(42)', delay=1000)
  File "<stdin>", line 1
    call_later(exec, 'print(42)', delay=1000)
                  ^
SyntaxError: invalid syntax

Which a pattern that someone might actually have used, though unlikely;

Or use it in a list comprehension:

>>> [exec(i) for i in ['print(42)', 'print(foo)']
  File "<stdin>", line 1
    [exec(i) for i in ['print(42)', 'print(foo)']
        ^
SyntaxError: invalid syntax

which is abuse of list comprehensions (use a for loop instead!).

If that is one table and have nothing to do with this - the simplest solution can be copy&paste to notepad then copy&paste back to excel :P

@scunlife's answer will work, but technically it ought to be

delete window.some_var; 

delete is supposed to be a no-op when the target isn't an object property. e.g.,

(function() {
   var foo = 123;
   delete foo; // wont do anything, foo is still 123
   var bar = { foo: 123 };
   delete bar.foo; // foo is gone
}());

But since global variables are actually members of the window object, it works.

When prototype chains are involved, using delete gets more complex because it only removes the property from the target object, and not the prototype. e.g.,

function Foo() {}
Foo.prototype = { bar: 123 };
var foo = new Foo();
// foo.bar is 123
foo.bar = 456;
// foo.bar is now 456
delete foo.bar;
// foo.bar is 123 again.

So be careful.

EDIT: My answer is somewhat inaccurate (see "Misconceptions" at the end). The link explains all the gory details, but the summary is that there can be big differences between browsers and depending on the object you are deleting from. delete object.someProp should generally be safe as long as object !== window. I still wouldn't use it to delete variables declared with var although you can under the right circumstances.

you should divide hours by 24 not 11
like this:
select to_char(sysdate - 2/24, 'dd-mon-yyyy HH24') from dual

If you are using CocoaPods. Similar thing has happened to me. Although this question is old someone like me might still be struggling. So for to help: after pod install it warns you about project files. I didn't notice till now. it says:

[!] Please close any current Xcode sessions and use ProjectFile.xcworkspace for this project from now on.

So basically, do not continue working on .xcodeproj after installing Pods. If you do linker won't find files.

You can bind resize using .resize() and run your code when the browser is resized. You need to also add an else condition to your if statement so that your css values toggle the old and the new, rather than just setting the new.

If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList instead of array:

List<Car> garage = new ArrayList<Car>();
garage.add(redCar);

Ganesan's answer above is not correct and StackOverflow is not letting me comment or Edit his post. So below is the correct answer. Ganesan has an incorrect facing "[" and is missing the stack isEmpty() check.

The below code will return true if the braces are properly matching.

public static boolean isValidExpression(String expression) {
    Map<Character, Character> openClosePair = new HashMap<Character, Character>();
    openClosePair.put(')', '(');
    openClosePair.put('}', '{');
    openClosePair.put(']', '[');

    Stack<Character> stack = new Stack<Character>();
    for(char ch : expression.toCharArray()) {
        if(openClosePair.containsKey(ch)) {
            if(stack.isEmpty() || stack.pop() != openClosePair.get(ch)) {
                return false;
            }
        } else if(openClosePair.values().contains(ch)) {
            stack.push(ch); 
        }
    }
    return stack.isEmpty();
}

EventHandler receives EventArgs as a parameter. To resolve your problem, you can build your own MyEventArgs.

 public enum MyEvents
 { 
    Event1 
 }

 public class MyEventArgs : EventArgs
 {
    public MyEvents MyEvent { get; set; }
 }

 public static event EventHandler<MyEventArgs> EventTriggered; 

 public static void Trigger(MyEvents ev) 
 { 
     if (EventTriggered != null) 
     {
         EventTriggered(null, new MyEventArgs { MyEvent = ev });
     } 
 } 

Lots of answers but no substance, like robots doing cut and paste on what's on their system. There is no need to set GOROOT as an environment variable. However, there is a beneficial need to set the GOPATH environment variable, and if not set it defaults to ${HOME}/go/ folder.

It is the PATH environment variable that you must pay attention because this variable is the variable that can change your go version. Not GOROOT! Forget GOROOT.

Now, if you switch or change to a new go version, your downloaded packages will use the default $HOME/go folder and it will mixed-up with whatever your previous go version was. This is not good.

Therefore, this is where GOPATH you need to define in order to isolate downloaded packages of the new go version.

In summary, forget GOROOT. Think more on GOPATH.

Use this to remove HTML tags from string in JavaScript:

const strippedString = htmlString.replace(/(<([^>]+)>)/gi, "");

console.log(strippedString);

Experimenting more, the underlying cause in my app (calling goog.userAgent.adobeReader) was accessing Adobe Reader via an ActiveXObject on the page with the link to the PDF. This minimal test case causes the gray screen for me (however removing the ActiveXObject causes no gray screen).

<!DOCTYPE html>
<html lang="en">

    </script>
    <a target="_blank" href="http://partners.adobe.com/public/developer/en/xml/AdobeXMLFormsSamples.pdf">link</a>
  </body>
</html>

I'm very interested if others are able to reproduce the problem with this test case and following the steps from my other post ("I don't have an exact solution...") on a "slow" computer.

Sorry for posting a new answer, but I couldn't figure out how to add a code block in a comment on my previous post.

For a video example of this minimal test case, see: http://youtu.be/IgEcxzM6Kck

The best approach is Long.valueOf(str) as it relies on Long.valueOf(long) which uses an internal cache making it more efficient since it will reuse if needed the cached instances of Long going from -128 to 127 included.

Returns a Long instance representing the specified long value. If a new Long instance is not required, this method should generally be used in preference to the constructor Long(long), as this method is likely to yield significantly better space and time performance by caching frequently requested values. Note that unlike the corresponding method in the Integer class, this method is not required to cache values within a particular range.

Thanks to auto-unboxing allowing to convert a wrapper class's instance into its corresponding primitive type, the code would then be:

long val = Long.valueOf(str);

Please note that the previous code can still throw a NumberFormatException if the provided String doesn't match with a signed long.

Generally speaking, it is a good practice to use the static factory method valueOf(str) of a wrapper class like Integer, Boolean, Long, ... since most of them reuse instances whenever it is possible making them potentially more efficient in term of memory footprint than the corresponding parse methods or constructors.

Excerpt from Effective Java Item 1 written by Joshua Bloch:

You can often avoid creating unnecessary objects by using static factory methods (Item 1) in preference to constructors on immutable classes that provide both. For example, the static factory method Boolean.valueOf(String) is almost always preferable to the constructor Boolean(String). The constructor creates a new object each time it’s called, while the static factory method is never required to do so and won’t in practice.

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

You need to add the source from where you're loading the data.

For Example:

$("#step1Content").load("yourpage.html");

Hope It will help you.

jQuery Data is a different concept than HTML. removeData is not for removing element content, it's for removing data items you've previously stored.

Just do

divToUpdate.html("");

or

divToUpdate.empty();

SOLUTION
Remove the Quotes around the /p:PublishDir setting

i.e.
Instead of quotes

/p:PublishDir="\\BSIIS3\c$\DATA\WEBSITES\benesys.net\benesys.net\TotalEducationTest\"  

Use no quotes

/p:PublishDir=\\BSIIS3\c$\DATA\WEBSITES\benesys.net\benesys.net\TotalEducationTest\  

I am sorry I did not post my finding sooner. I actually had to research again to see what needed to be changed. Who would have thought removing quotes would have worked? I discovered this when viewing a coworkers build for another solution and noticed it did not have quotes.

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

There is an object serialization module, with the serialize function you can serialize any object.

In MySQL Workbench you need an INDEX to edit, no need it to be PK (although adding a PK is a solution as well).

You can make a regular INDEX or compound INDEX. That's all MySQL WB needs to fix the Read only thing (I have v. 6.2 with MariaDB v. 10.1.4):

Just right click table, select "Alter table..." then go to "Indexes" tab. In the left pane put a custom name for your index, and in the middle pane checkmark one (make sure the vale will be unique) or more fields (just make sure the combination is unique)

To delete untracked on *nix without the purge extension you can use

hg pull
hg update -r MY_BRANCH -C
hg status -un|xargs rm

Which is using

update -r --rev REV revision

update -C --clean discard uncommitted changes (no backup)

status -u --unknown show only unknown (not tracked) files

status -n --no-status hide status prefix

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

As Brad Wilson states in his answer here:

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Try using :-

if (!ModelState.IsValid)
{
    var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

    // Breakpoint, Log or examine the list with Exceptions.
}

Without any external tool you can simply accomplish this on Windows 7 or 8, by opening up the Resource monitor and on the CPU or Overview tab right clicking on the process and selecting Suspend Process. The Resource monitor can be started from the Performance tab of the Task manager.

Ideally we should not handle/catch errors. But there may be cases where we need to do, based on requirement of framework or application. Say i have a XML Parser daemon which implements DOM Parser which consumes more Memory. If there is a requirement like Parser thread should not be died when it gets OutOfMemoryError, instead it should handle it and send a message/mail to administrator of application/framework.

You have to add the reference to System.configuration in your solution. Also, include using System.Configuration;. Once you do that, you'll have access to all the configuration settings.

You only need a minimal change; single-quote the here-document delimiter after <<.

cat <<'EOF' >> brightup.sh

or equivalently backslash-escape it:

cat <<\EOF >>brightup.sh

Without quoting, the here document will undergo variable substitution, backticks will be evaluated, etc, like you discovered.

If you need to expand some, but not all, values, you need to individually escape the ones you want to prevent.

cat <<EOF >>brightup.sh
#!/bin/sh
# Created on $(date # : <<-- this will be evaluated before cat;)
echo "\$HOME will not be evaluated because it is backslash-escaped"
EOF

will produce

#!/bin/sh
# Created on Fri Feb 16 11:00:18 UTC 2018
echo "$HOME will not be evaluated because it is backslash-escaped"

As suggested by @fedorqui, here is the relevant section from man bash:

Here Documents

This type of redirection instructs the shell to read input from the current source until a line containing only delimiter (with no trailing blanks) is seen. All of the lines read up to that point are then used as the standard input for a command.

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. In the latter case, the character sequence \<newline> is ignored, and \ must be used to quote the characters \, $, and `.

It's not fading to "black transparent" or "white transparent". It's just showing whatever color is "behind" the image, which is not the image's background color - that color is completely hidden by the image.

If you want to fade to black(ish), you'll need a black container around the image. Something like:

.ctr {
    margin: 0; 
    padding: 0;
    background-color: black;
    display: inline-block;
}

and

<div class="ctr"><img ... /></div>

It really depends on the sort of data you're bringing back. Since a DataSet is (in effect) just a collection of DataTable objects, you can return multiple distinct sets of data into a single, and therefore more manageable, object.

Performance-wise, you're more likely to get inefficiency from unoptimized queries than from the "wrong" choice of .NET construct. At least, that's been my experience.

Change position:absolute to position:fixed;.

Example can be found in this jsFiddle.

The naive algorithm, which is what you've got once you correct it as noted in comments, is O(n^3).

There do exist algorithms that reduce this somewhat, but you're not likely to find an O(n^2) implementation. I believe the question of the most efficient implementation is still open.

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Try the following:

document.getElementById("id").setAttribute("disabled", "disabled");

Here's a possible solution:

For 3 columns use li width as 33%, for 4 columns use 25% and so on.

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

re.Match objects have a number of methods to help you with this:

>>> m = re.search("is", String)
>>> m.span()
(2, 4)
>>> m.start()
2
>>> m.end()
4

To change the panel's background color, use the following code:

myplot + theme(panel.background = element_rect(fill = 'green', colour = 'red'))

To change the color of the plot (but not the color of the panel), you can do:

myplot + theme(plot.background = element_rect(fill = 'green', colour = 'red'))

See here for more theme details Quick reference sheet for legends, axes and themes.

Is there any other way to convert that array into string ?

Yes there is. serialize(). It can convert various data types (including object and arrays) into a string representation which you can unserialize() at a later time. Serializing an associative array such as Array(18 => 'Somthing') will preserve both keys and values:

<?php
$a = array(18 => 'Something');
echo serialize($a);                                   // a:1:{i:18;s:9:"Something";}
var_dump(unserialize('a:1:{i:18;s:9:"Something";}')); // array(1) {
                                                      //   [18]=>
                                                      //   string(9) "Something"
                                                      // }

Python-3.x:

"aabc".count("a")

str.count(sub[, start[, end]])

Return the number of non-overlapping occurrences of substring sub in the range [start, end]. Optional arguments start and end are interpreted as in slice notation.

if you want to emebed the canvas you can use this snippet

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <canvas id=canvas width=200 height=200></canvas>
    <iframe id='img' width=200 height=200></iframe>
    <script>
        window.onload = function() {
            var canvas = document.getElementById("canvas");
            var context = canvas.getContext("2d");
            context.fillStyle = "green";
            context.fillRect(50, 50, 100, 100);
            document.getElementById('img').src = canvas.toDataURL("image/jpeg");
            console.log(canvas.toDataURL("image/jpeg"));
        }
    </script>
</body>
</html>

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

I just had this issue.. I just added the MinGW\bin directory to the path environment variable, and it solved the issue.

You're using jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead you can use on method and bind the JavaScript load event:

 $(window).on('load', function () {
      alert("Window Loaded");
 });

On the following option:

WebElement option = select.getFirstSelectedOption();
option.getText();

If from the method getText() you get a blank, you can get the string from the value of the option using the method getAttribute:

WebElement option = select.getFirstSelectedOption();
option.getAttribute("value");

This is an old question, but everybody fails to mention that Enums are actually Serializable and therefore can perfectly be added to an Intent as an extra. Like this:

public enum AwesomeEnum {
  SOMETHING, OTHER;
}

intent.putExtra("AwesomeEnum", AwesomeEnum.SOMETHING);

AwesomeEnum result = (AwesomeEnum) intent.getSerializableExtra("AwesomeEnum");

The suggestion to use static or application-wide variables is a really bad idea. This really couples your activities to a state managing system, and it is hard to maintain, debug and problem bound.

ALTERNATIVES:

A good point was noted by tedzyc about the fact that the solution provided by Oderik gives you an error. However, the alternative offered is a bit cumbersome to use (even using generics).

If you are really worried about the performance of adding the enum to an Intent I propose these alternatives instead:

OPTION 1:

public enum AwesomeEnum {
  SOMETHING, OTHER;
  private static final String name = AwesomeEnum.class.getName();
  public void attachTo(Intent intent) {
    intent.putExtra(name, ordinal());
  }
  public static AwesomeEnum detachFrom(Intent intent) {
    if(!intent.hasExtra(name)) throw new IllegalStateException();
    return values()[intent.getIntExtra(name, -1)];
  }
}

Usage:

// Sender usage
AwesomeEnum.SOMETHING.attachTo(intent);
// Receiver usage
AwesomeEnum result = AwesomeEnum.detachFrom(intent);

OPTION 2: (generic, reusable and decoupled from the enum)

public final class EnumUtil {
    public static class Serializer<T extends Enum<T>> extends Deserializer<T> {
        private T victim;
        @SuppressWarnings("unchecked") 
        public Serializer(T victim) {
            super((Class<T>) victim.getClass());
            this.victim = victim;
        }
        public void to(Intent intent) {
            intent.putExtra(name, victim.ordinal());
        }
    }
    public static class Deserializer<T extends Enum<T>> {
        protected Class<T> victimType;
        protected String name;
        public Deserializer(Class<T> victimType) {
            this.victimType = victimType;
            this.name = victimType.getName();
        }
        public T from(Intent intent) {
            if (!intent.hasExtra(name)) throw new IllegalStateException();
            return victimType.getEnumConstants()[intent.getIntExtra(name, -1)];
        }
    }
    public static <T extends Enum<T>> Deserializer<T> deserialize(Class<T> victim) {
        return new Deserializer<T>(victim);
    }
    public static <T extends Enum<T>> Serializer<T> serialize(T victim) {
        return new Serializer<T>(victim);
    }
}

Usage:

// Sender usage
EnumUtil.serialize(AwesomeEnum.Something).to(intent);
// Receiver usage
AwesomeEnum result = 
EnumUtil.deserialize(AwesomeEnum.class).from(intent);

OPTION 3 (with Kotlin):

It's been a while, but since now we have Kotlin, I thought I would add another option for the new paradigm. Here we can make use of extension functions and reified types (which retains the type when compiling).

inline fun <reified T : Enum<T>> Intent.putExtra(victim: T): Intent =
    putExtra(T::class.java.name, victim.ordinal)

inline fun <reified T: Enum<T>> Intent.getEnumExtra(): T? =
    getIntExtra(T::class.java.name, -1)
        .takeUnless { it == -1 }
        ?.let { T::class.java.enumConstants[it] }

There are a few benefits of doing it this way.

• We don't require the "overhead" of an intermediary object to do the serialization as it's all done in place thanks to inline which will replace the calls with the code inside the function.
• The functions are more familiar as they are similar to the SDK ones.
• The IDE will autocomplete these functions which means there is no need to have previous knowledge of the utility class.

One of the downsides is that, if we change the order of the Emums, then any old reference will not work. This can be an issue with things like Intents inside pending intents as they may survive updates. However, for the rest of the time, it should be ok.

It's important to note that other solutions, like using the name instead of the position, will also fail if we rename any of the values. Although, in those cases, we get an exception instead of the incorrect Enum value.

Usage:

// Sender usage
intent.putExtra(AwesomeEnum.SOMETHING)
// Receiver usage
val result = intent.getEnumExtra<AwesomeEnum>()

I don't think I saw anyone suggest this and the OP just said "script" so...

I needed to solve the same problem and my most comfortable language is Python.

I used the paramiko library. Furthermore, I also needed to issue commands for which I would need escalated permissions using sudo. It turns out sudo can accept its password via stdin via the "-S" flag! See below:

import paramiko

ssh_client = paramiko.SSHClient()

# To avoid an "unknown hosts" error. Solve this differently if you must...
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# This mechanism uses a private key.
pkey = paramiko.RSAKey.from_private_key_file(PKEY_PATH)

# This mechanism uses a password.
# Get it from cli args or a file or hard code it, whatever works best for you
password = "password"

ssh_client.connect(hostname="my.host.name.com",
                       username="username",
                       # Uncomment one of the following...
                       # password=password
                       # pkey=pkey
                       )

# do something restricted
# If you don't need escalated permissions, omit everything before "mkdir"
command = "echo {} | sudo -S mkdir /var/log/test_dir 2>/dev/null".format(password)

# In order to inspect the exit code
# you need go under paramiko's hood a bit
# rather than just using "ssh_client.exec_command()"
chan = ssh_client.get_transport().open_session()
chan.exec_command(command)

exit_status = chan.recv_exit_status()

if exit_status != 0:
    stderr = chan.recv_stderr(5000)

# Note that sudo's "-S" flag will send the password prompt to stderr
# so you will see that string here too, as well as the actual error.
# It was because of this behavior that we needed access to the exit code
# to assert success.

    logger.error("Uh oh")
    logger.error(stderr)
else:
    logger.info("Successful!")

Hope this helps someone. My use case was creating directories, sending and untarring files and starting programs on ~300 servers as a time. As such, automation was paramount. I tried sshpass, expect, and then came up with this.

This exception is thrown when an application attempts to perform a networking operation on its main thread. If your task took above five seconds, it takes a force close.

Run your code in AsyncTask:

class RetrieveFeedTask extends AsyncTask<String, Void, Boolean> {

    protected RSSFeed doInBackground(String... urls) {
       // TODO: Connect
    }

    protected void onPostExecute(RSSFeed feed) {
        // TODO: Check this.exception
        // TODO: Do something with the feed
    }
}

Unlike Virtualization, containerization uses the same host os. So the container built on linux can not be run on windows and vice versa.

In windows, you have to take help of virtuallization (using Hyper-v) to have same os as your containers's os and then you should be able to run the same.

Docker for windows is similar app which is built on Hyper-v and helps in running linux docker container on windows. But as far as I know, there is nothing as such which helps run windows containers on linux.

They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"

In addition, for those looking to replace more than one character in a column, you can do it using regular expressions:

import re
chars_to_remove = ['.', '-', '(', ')', '']
regular_expression = '[' + re.escape (''. join (chars_to_remove)) + ']'

df['string_col'].str.replace(regular_expression, '', regex=True)

Well, you can use xpath utility. I guess perl's XML::Xpath contains it.

Use given lines in OnActionExecuting for Action and Controller name.

string actionName = this.ControllerContext.RouteData.Values["action"].ToString();

string controllerName = this.ControllerContext.RouteData.Values["controller"].ToString();

i = ['title', 'email', 'password2', 'password1', 'first_name', 
     'last_name', 'next', 'newsletter']
a, b = i.index('password2'), i.index('password1')
i[b], i[a] = i[a], i[b]

Modal Popups in Interface Builder (Storyboards)

Step 1

On the ViewController you want as your modal popup, make the background color of the root UIView clear. Tip: Do not use the root UIView as your popup. Add a new UIView that is smaller to be your popup.

Step 2

Create a Segue to the ViewController that has your popup. Select "Present Modally".

Two Methods To Create Popup From Here

Method One - Using the Segue

Select the Segue and change Presentation to "Over Current Context":

Method Two - Using the View Controller

Select the ViewController Scene that is your popup. In Attributes Inspector, under View Controller section, set Presentation to "Over Current Context":

Either method will work. That should do it!

Here is the answer for those of you looking like I did all over the web trying to find out how to do this task. Uploading a photo to a server with the file name stored in a mysql database and other form data you want in your Database. Please let me know if it helped.

Firstly the form you need:

    <form method="post" action="addMember.php" enctype="multipart/form-data">
    <p>
              Please Enter the Band Members Name.
            </p>
            <p>
              Band Member or Affiliates Name:
            </p>
            <input type="text" name="nameMember"/>
            <p>
              Please Enter the Band Members Position. Example:Drums.
            </p>
            <p>
              Band Position:
            </p>
            <input type="text" name="bandMember"/>
            <p>
              Please Upload a Photo of the Member in gif or jpeg format. The file name should be named after the Members name. If the same file name is uploaded twice it will be overwritten! Maxium size of File is 35kb.
            </p>
            <p>
              Photo:
            </p>
            <input type="hidden" name="size" value="350000">
            <input type="file" name="photo"> 
            <p>
              Please Enter any other information about the band member here.
            </p>
            <p>
              Other Member Information:
            </p>
<textarea rows="10" cols="35" name="aboutMember">
</textarea>
            <p>
              Please Enter any other Bands the Member has been in.
            </p>
            <p>
              Other Bands:
            </p>
            <input type="text" name="otherBands" size=30 />
            <br/>
            <br/>
            <input TYPE="submit" name="upload" title="Add data to the Database" value="Add Member"/>
          </form>

Then this code processes you data from the form:

   <?php

// This is the directory where images will be saved
$target = "your directory";
$target = $target . basename( $_FILES['photo']['name']);

// This gets all the other information from the form
$name=$_POST['nameMember'];
$bandMember=$_POST['bandMember'];
$pic=($_FILES['photo']['name']);
$about=$_POST['aboutMember'];
$bands=$_POST['otherBands'];


// Connects to your Database
mysqli_connect("yourhost", "username", "password") or die(mysqli_error()) ;
mysqli_select_db("dbName") or die(mysqli_error()) ;

// Writes the information to the database
mysqli_query("INSERT INTO tableName (nameMember,bandMember,photo,aboutMember,otherBands)
VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;

// Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{

// Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {

// Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

This is because you select not a theme of your project. Try to do next:

In the manual for GNU make, they talk about this specific example when describing the value function:

The value function provides a way for you to use the value of a variable without having it expanded. Please note that this does not undo expansions which have already occurred; for example if you create a simply expanded variable its value is expanded during the definition; in that case the value function will return the same result as using the variable directly.

The syntax of the value function is:

 $(value variable)

Note that variable is the name of a variable; not a reference to that variable. Therefore you would not normally use a ‘$’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)

The result of this function is a string containing the value of variable, without any expansion occurring. For example, in this makefile:

 FOO = $PATH

 all:
         @echo $(FOO)
         @echo $(value FOO)

The first output line would be ATH, since the “$P” would be expanded as a make variable, while the second output line would be the current value of your $PATH environment variable, since the value function avoided the expansion.

You can have a look at this article about pointers http://www.cplusplus.com/doc/tutorial/pointers/ and read the chapter : void pointers.

This also works for C language.

The void type of pointer is a special type of pointer. In C++, void represents the absence of type, so void pointers are pointers that point to a value that has no type (and thus also an undetermined length and undetermined dereference properties).

This allows void pointers to point to any data type, from an integer value or a float to a string of characters. But in exchange they have a great limitation: the data pointed by them cannot be directly dereferenced (which is logical, since we have no type to dereference to), and for that reason we will always have to cast the address in the void pointer to some other pointer type that points to a concrete data type before dereferencing it.

Check the path where you have generated the public key. You can also copy the id_rsa by using this command:

clip < ~/.ssh/id_rsa.pub

$(document).ready(function () {
            $('#Grid_Id').dataTable({
                "bPaginate": false
            });
        });

i have solved my problem using it.

you can try this

td.setAttribute("style", "font-weight:bold");

( child selector) was introduced in css2. div p{ } select all p elements decedent of div elements, whereas div > p selects only child p elements, not grand child, great grand child on so on.

<style>
  div p{  color:red  }       /* match both p*/
  div > p{  color:blue  }    /* match only first p*/

</style>

<div>
   <p>para tag, child and decedent of p.</p>
   <ul>
       <li>
            <p>para inside list. </p>
       </li>
   </ul>
</div>

If anyone is interested in getting the localized string from the property with DisplayAttribute and ResourceType like this:

[Display(Name = "Year", ResourceType = typeof(ArrivalsResource))]
public int Year { get; set; }

Use the following after displayAttribute != null (as shown above by @alex' answer):

ResourceManager resourceManager = new ResourceManager(displayAttribute.ResourceType);
var entry = resourceManager.GetResourceSet(Thread.CurrentThread.CurrentUICulture, true, true)
                           .OfType<DictionaryEntry>()
                           .FirstOrDefault(p => p.Key.ToString() == displayAttribute.Name);

return entry.Value.ToString();

echo "|$COMMAND|"|tr '\n' ' '

will replace the newline (in POSIX/Unix it's not a carriage return) with a space.

To be honest I would think about switching away from bash to something more sane though. Or avoiding generating this malformed data in the first place.

Hmmm, this seems like it could be a horrible security hole as well, depending on where the data is coming from.

There are different methods to deserialize json string to an object. All above methods are acceptable but I suggest using a library to prevent duplicate key issues or serializing/deserializing of nested objects.

Pykson, is a JSON Serializer and Deserializer for Python which can help you achieve. Simply define Payload class model as JsonObject then use Pykson to convert json string to object.

from pykson import Pykson, JsonObject, StringField

class Payload(pykson.JsonObject):
    action = StringField()
    method = StringField()
    data = StringField()

json_text = '{"action":"print","method":"onData","data":"Madan Mohan"}'
payload = Pykson.from_json(json_text, Payload)

The out of memory suggestion doesn't seem like a bad lead.

What is your program doing that it gets this error?

Is it creating a great many windows or controls? Does it create them programatically as opposed to at design time? If so, do you do this in a loop? Is that loop infinite? Are you consuming staggering boatloads of memory in some other way?

What happens when you watch the memory used by your application in task manager? Does it skyrocket to the moon? Or better yet, as suggested above use process monitor to dive into the details.

I know it may be too late to answer this, but this worked for me in a great way:

1. Stringify your javascript object (json) with var st = JSON.stringify(your_object);

2. Pass your POST data as "string" (maybe using jQuery: $.post('foo.php',{data:st},function(data){... });

3. Decode your data on the server-side processing: $data = json_decode($_POST['data']);

That's it... you can freely use your data.

Multi-dimensional arrays and single arrays are handled as normal arrays. To access them just do the normal $foo[4].

Associative arrays (javsacript objects) are handled as php objects (classes). To access them just do it like classes: $foo->bar.

Use HTML template instead!

Since the accepted answer would represent overloading script method, I would like to suggest another which is, in my opinion, much cleaner and more secure due to XSS risks which come with overloading scripts.

I made a demo to show you how to use it in an action and how to inject one template into another, edit and then add to the document DOM.

example html

<template id="mytemplate">
  <style>
     .image{
        width: 100%;
        height: auto;
     }
  </style>
  <a href="#" class="list-group-item">
    <div class="image">
      <img src="" />
    </div>
    <p class="list-group-item-text"></p>
  </a>
</template>

example js

// select
var t = document.querySelector('#mytemplate');

// set
t.content.querySelector('img').src = 'demo.png';
t.content.querySelector('p').textContent= 'demo text';

// add to document DOM
var clone = document.importNode(t.content, true); // where true means deep copy
document.body.appendChild(clone);

HTML <template>

• +Its content is effectively inert until activated. Essentially, your markup is hidden DOM and does not render.

• +Any content within a template won't have side effects. Scripts don't run, images don't load, audio doesn't play ...until the template is used.

• +Content is considered not to be in the document. Using document.getElementById() or querySelector() in the main page won't return child nodes of a template.

• +Templates can be placed anywhere inside of <head>, <body>, or <frameset> and can contain any type of content which is allowed in those elements. Note that "anywhere" means that <template> can safely be used in places that the HTML parser disallows.

Fall back

Browser support should not be an issue but if you want to cover all possibilities you can make an easy check:

To feature detect <template>, create the DOM element and check that the .content property exists:

function supportsTemplate() {
  return 'content' in document.createElement('template');
}

if (supportsTemplate()) {
  // Good to go!
} else {
  // Use old templating techniques or libraries.
}

Some insights about Overloading script method

• +Nothing is rendered - the browser doesn't render this block because the <script> tag has display:none by default.
• +Inert - the browser doesn't parse the script content as JS because its type is set to something other than "text/javascript".
• -Security issues - encourages the use of .innerHTML. Run-time string parsing of user-supplied data can easily lead to XSS vulnerabilities.

If you specifically want to use SwingX-WS, then have a look at XmlHttpRequest and JSONHttpRequest.

More on those classes in the XMLHttpRequest and Swing blog post.

Test with a setTimeout, that worked for me and I could submit my form, refers to this answer https://stackoverflow.com/a/779785/5510314

$(document).ready(function () {
    $("#btnSubmit").click(function () {
        setTimeout(function () { disableButton(); }, 0);
    });

    function disableButton() {
        $("#btnSubmit").prop('disabled', true);
    }
});

In simple terms you need to build your payload into a key array

payload = {'key1': 'value1', 'key2': 'value2'}

Then send the payload directly to the action

this.$store.dispatch('yourAction', payload)

No change in your action

yourAction: ({commit}, payload) => {
  commit('YOUR_MUTATION',  payload )
},

In your mutation call the values with the key

'YOUR_MUTATION' (state,  payload ){
  state.state1 = payload.key1
  state.state2 =  payload.key2
},

Put the part from BEGIN....END{} inside a file and name it like my.awk.

And then execute it like below:

awk -f my.awk life.csv >output.txt

Also I see a field separator as ,. You can add that in the begin block of the .awk file as FS=","

This works perfectly

<i class="fa fa-power-off text-gray" style="transform: rotate(90deg);"></i>

For a div-Element you could just set the opacity via a class to enable or disable the effect.

.mute-all {
   opacity: 0.4;
}

With the data as a pd.Series and scipy.stats, calculating the entropy of a given quantity is pretty straightforward:

import pandas as pd
import scipy.stats

def ent(data):
    """Calculates entropy of the passed `pd.Series`
    """
    p_data = data.value_counts()           # counts occurrence of each value
    entropy = scipy.stats.entropy(p_data)  # get entropy from counts
    return entropy

Note: scipy.stats will normalize the provided data, so this doesn't need to be done explicitly, i.e. passing an array of counts works fine.

Using Typescript?

Here's a quick sleep() implementation that can be awaited. This is as similar as possible to the top answer. It's functionally equivalent except ms is typed as number for typescript.

const sleep = (ms: number) =>
  new Promise((resolve) => setTimeout(resolve, ms));

async function demo() {
  console.log('Taking a break for 2s (2000ms)...');
  await sleep(2000);
  console.log('Two seconds later');
}

demo();

This is it. await sleep(<duration>).

Note that,

1. await can only be executed in functions prefixed with the async keyword, or at the top level of your script in some environments (e.g. the Chrome DevTools console, or Runkit).
2. await only pauses the current async function

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

I just wrote a blog post on saving an object's data to Binary, XML, or Json. You are correct that you must decorate your classes with the [Serializable] attribute, but only if you are using Binary serialization. You may prefer to use XML or Json serialization. Here are the functions to do it in the various formats. See my blog post for more details.

Binary

/// <summary>
/// Writes the given object instance to a binary file.
/// <para>Object type (and all child types) must be decorated with the [Serializable] attribute.</para>
/// <para>To prevent a variable from being serialized, decorate it with the [NonSerialized] attribute; cannot be applied to properties.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the binary file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the binary file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToBinaryFile<T>(string filePath, T objectToWrite, bool append = false)
{
    using (Stream stream = File.Open(filePath, append ? FileMode.Append : FileMode.Create))
    {
        var binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        binaryFormatter.Serialize(stream, objectToWrite);
    }
}

/// <summary>
/// Reads an object instance from a binary file.
/// </summary>
/// <typeparam name="T">The type of object to read from the binary file.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the binary file.</returns>
public static T ReadFromBinaryFile<T>(string filePath)
{
    using (Stream stream = File.Open(filePath, FileMode.Open))
    {
        var binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        return (T)binaryFormatter.Deserialize(stream);
    }
}

XML

Requires the System.Xml assembly to be included in your project.

/// <summary>
/// Writes the given object instance to an XML file.
/// <para>Only Public properties and variables will be written to the file. These can be any type though, even other classes.</para>
/// <para>If there are public properties/variables that you do not want written to the file, decorate them with the [XmlIgnore] attribute.</para>
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToXmlFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
{
    TextWriter writer = null;
    try
    {
        var serializer = new XmlSerializer(typeof(T));
        writer = new StreamWriter(filePath, append);
        serializer.Serialize(writer, objectToWrite);
    }
    finally
    {
        if (writer != null)
            writer.Close();
    }
}

/// <summary>
/// Reads an object instance from an XML file.
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object to read from the file.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the XML file.</returns>
public static T ReadFromXmlFile<T>(string filePath) where T : new()
{
    TextReader reader = null;
    try
    {
        var serializer = new XmlSerializer(typeof(T));
        reader = new StreamReader(filePath);
        return (T)serializer.Deserialize(reader);
    }
    finally
    {
        if (reader != null)
            reader.Close();
    }
}

Json

You must include a reference to Newtonsoft.Json assembly, which can be obtained from the Json.NET NuGet Package.

/// <summary>
/// Writes the given object instance to a Json file.
/// <para>Object type must have a parameterless constructor.</para>
/// <para>Only Public properties and variables will be written to the file. These can be any type though, even other classes.</para>
/// <para>If there are public properties/variables that you do not want written to the file, decorate them with the [JsonIgnore] attribute.</para>
/// </summary>
/// <typeparam name="T">The type of object being written to the file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToJsonFile<T>(string filePath, T objectToWrite, bool append = false) where T : new()
{
    TextWriter writer = null;
    try
    {
        var contentsToWriteToFile = JsonConvert.SerializeObject(objectToWrite);
        writer = new StreamWriter(filePath, append);
        writer.Write(contentsToWriteToFile);
    }
    finally
    {
        if (writer != null)
            writer.Close();
    }
}

/// <summary>
/// Reads an object instance from an Json file.
/// <para>Object type must have a parameterless constructor.</para>
/// </summary>
/// <typeparam name="T">The type of object to read from the file.</typeparam>
/// <param name="filePath">The file path to read the object instance from.</param>
/// <returns>Returns a new instance of the object read from the Json file.</returns>
public static T ReadFromJsonFile<T>(string filePath) where T : new()
{
    TextReader reader = null;
    try
    {
        reader = new StreamReader(filePath);
        var fileContents = reader.ReadToEnd();
        return JsonConvert.DeserializeObject<T>(fileContents);
    }
    finally
    {
        if (reader != null)
            reader.Close();
    }
}

Example

// Write the contents of the variable someClass to a file.
WriteToBinaryFile<SomeClass>("C:\someClass.txt", object1);

// Read the file contents back into a variable.
SomeClass object1= ReadFromBinaryFile<SomeClass>("C:\someClass.txt");

I actually hate obj files littering the source trees. I usually setup projects so that they output obj files outside source tree. For C# projects I usually use

 <IntermediateOutputPath>..\..\obj\$(AssemblyName)\$(Configuration)\</IntermediateOutputPath>

For C++ projects

 IntermediateDirectory="..\..\obj\$(ProjectName)\$(ConfigurationName)"

Give each input a name attribute. Only the clicked input's name attribute will be sent to the server.

<input type="submit" name="publish" value="Publish">
<input type="submit" name="save" value="Save">

And then

<?php
    if (isset($_POST['publish'])) {
        # Publish-button was clicked
    }
    elseif (isset($_POST['save'])) {
        # Save-button was clicked
    }
?>

Edit: Changed value attributes to alt. Not sure this is the best approach for image buttons though, any particular reason you don't want to use input[type=image]?

Edit: Since this keeps getting upvotes I went ahead and changed the weird alt/value code to real submit inputs. I believe the original question asked for some sort of image buttons but there are so much better ways to achieve that nowadays instead of using input[type=image].

For Jackson to serialize that class, the SomeString field needs to either be public (right now it's package level isolation) or you need to define getter and setter methods for it.

/**
     * Forbids special characters and decimals
     * Allows numbers only
     * */
    const numbersOnly = (evt) => {

        let charCode = (evt.which) ? evt.which : evt.keyCode;
        if (charCode === 46 && charCode > 31 && (charCode < 48 || charCode > 57)) {
            return false;
        }

        let inputResult = /^[0-9]*$/.test(evt.target.value);
        if (!inputResult) {
            evt.target.value = evt.target.value.replace(/[^a-z0-9\s]/gi, '');
        }

        return true;
    }

I found this to be more cross-browser compatible:

$(document).keypress(function(event) {
    var keycode = event.keyCode || event.which;
    if(keycode == '13') {
        alert('You pressed a "enter" key in somewhere');    
    }
});

As a summary

import sys
import re

f = sys.argv[1]
find = sys.argv[2]
replace = sys.argv[3]
with open (f, "r") as myfile:
     s=myfile.read()
ret = re.sub(find,replace, s)   # <<< This is where the magic happens
print ret

$(function ()    {
    $('<div>').dialog({
        modal: true,
        open: function ()
        {
            $(this).load('Sample.htm');
        },         
        height: 400,
        width: 400,
        title: 'Dynamically Loaded Page'
    });
});

That's very nice, however in order to simulate some time passing we need to run a command that takes some time and that's very clear in second example.

However, the style of using a for loop to do some functionality forever takes a lot of device resources and instead we can use the Garbage Collector to do some thing like that.

We can see this modification in the code from the same book CLR Via C# Third Ed.

using System;
using System.Threading;

public static class Program {

   public static void Main() {
      // Create a Timer object that knows to call our TimerCallback
      // method once every 2000 milliseconds.
      Timer t = new Timer(TimerCallback, null, 0, 2000);
      // Wait for the user to hit <Enter>
      Console.ReadLine();
   }

   private static void TimerCallback(Object o) {
      // Display the date/time when this method got called.
      Console.WriteLine("In TimerCallback: " + DateTime.Now);
      // Force a garbage collection to occur for this demo.
      GC.Collect();
   }
}

There's actually a pretty sollution:

function updateArray(context, targetName, callback) {
    context[targetName] = context[targetName].map(callback);
}

var myArray = ['a', 'b', 'c'];
updateArray(this, 'myArray', item => {return '_' + item});

console.log(myArray); //(3) ["_a", "_b", "_c"]

I believe you are using Bootstrap 3. If so, please try this code, here is the bootply

<header>
    <div class="navbar navbar-static-top navbar-default">
        <div class="navbar-header">
            <a class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                <span class="glyphicon glyphicon-th-list"></span>
            </a>
        </div>
        <div class="container" style="background:yellow;">
            <a href="/">
                <img src="img/logo.png" class="logo img-responsive">
            </a>

            <nav class="navbar-collapse collapse pull-right" style="line-height:150px; height:150px;">
                <ul class="nav navbar-nav" style="display:inline-block;">
                    <li><a href="">Portfolio</a></li>
                    <li><a href="">Blog</a></li>
                    <li><a href="">Contact</a></li>
                </ul>
            </nav>
        </div>
    </div>
</header>

You can use a sort function :

var myarray=[25, 8, 7, 41]
myarray.sort( function(a,b) { return b - a; } );
// 7 8 25 41

Look at http://www.javascriptkit.com/javatutors/arraysort.shtml

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

In your controller class, create an action method you will hook the button up to in Interface Builder. Inside that method you can trim your string like this:

if ([string length] > 0) {
    string = [string substringToIndex:[string length] - 1];
} else {
    //no characters to delete... attempting to do so will result in a crash
}

If you want a fancy way of doing this in just one line of code you could write it as:

string = [string substringToIndex:string.length-(string.length>0)];

*Explanation of fancy one-line code snippet:

If there is a character to delete (i.e. the length of the string is greater than 0)
     (string.length>0) returns 1 thus making the code return:
          string = [string substringToIndex:string.length-1];

If there is NOT a character to delete (i.e. the length of the string is NOT greater than 0)
     (string.length>0) returns 0 thus making the code return:
          string = [string substringToIndex:string.length-0];
     Which prevents crashes.

In modern browsers, you can simply use css:

th {
  position: sticky;
  top: 0;
  z-index: 2;
}

You can use Polyfill

if (!Array.prototype.filterIndex) {
Array.prototype.filterIndex = function (func, thisArg) {

    'use strict';
    if (!((typeof func === 'Function' || typeof func === 'function') && this))
        throw new TypeError();

    let len = this.length >>> 0,
        res = new Array(len), // preallocate array
        t = this, c = 0, i = -1;

    let kValue;
    if (thisArg === undefined) {
        while (++i !== len) {
            // checks to see if the key was set
            if (i in this) {
                kValue = t[i]; // in case t is changed in callback
                if (func(t[i], i, t)) {
                    res[c++] = i;
                }
            }
        }
    }
    else {
        while (++i !== len) {
            // checks to see if the key was set
            if (i in this) {
                kValue = t[i];
                if (func.call(thisArg, t[i], i, t)) {
                    res[c++] = i;
                }
            }
        }
    }

    res.length = c; // shrink down array to proper size
    return res;
};

}

Use it like this:

[2,23,1,2,3,4,52,2].filterIndex(element => element === 2)

result: [0, 3, 7]

In Ubuntu, you can simply install Open JDK by following commands.

sudo apt-get update    
sudo apt-get install default-jdk

You can check the java version by following the command.

java -version

If you want to install Oracle JDK 8 follow the below commands.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

If you want to switch java versions you can try below methods.

vi ~/.bashrc and add the following line export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_221 (path/jdk folder)

or

sudo vi /etc/profile and add the following lines

#JAVA_HOME=/usr/lib/jvm/jdk1.8.0_221
JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME
export JRE_HOME
export PATH

You can comment on the other version. This needs to sign out and sign back in to use. If you want to try it on the go you can type the below command in the same terminal. It'll only update the java version for a particular terminal.

source /etc/profile

You can always check the java version by java -version command.

In my IE11, works normally. Version: 11.306.10586.0

We can test if ActiveX works at IE, in this site: http://www.pcpitstop.com/testax.asp

On CentOS 7, the following works:

yum install php-soap

This will automatically create a soap.ini under /etc/php.d.

The extension itself for me lives in /usr/lib64/php/modules. You can confirm your extension directory by doing:

php -i | grep extension_dir

Once this has been installed, you can simply restart Apache using the new service manager like so:

systemctl restart httpd

Thanks to Matt Browne for the info about /etc/php.d.

Here is how I add parameters:

sprocCommand.Parameters.Add(New SqlParameter("@Date_Of_Birth",Data.SqlDbType.DateTime))
sprocCommand.Parameters("@Date_Of_Birth").Value = DOB

I am assuming when you write out DOB there are no quotes.

Are you using a third-party control to get the date? I have had problems with the way the text value is generated from some of them.

Lastly, does it work if you type in the .Value attribute of the parameter without referencing DOB?

There are many tutorials and answers here how to add your script to be included in the page. But what I couldn't find is how to structure that code so it will work properly. This is due the $ being not used in this form of JQuery.

So here is my code and you can use that as a template.

jQuery(document).ready(function( $ ){
  $("#btnCalculate").click(function () {
        var val1 = $(".visits").val();
        var val2 = $(".collection").val();
        var val3 = $(".percent").val();
        var val4 = $(".expired").val();
        var val5 = $(".payer").val();
        var val6 = $(".deductible").val(); 
        var result = val1 * (val3 / 100) * 10 * 0.25;
        var result2 = val1 * val2 * (val4 / 100) * 0.2;
        var result3 = val1 * val2 * (val5 / 100) * 0.2;
        var result4 = val1 * val2 * (val6 / 100) * 0.1;
        var val7 = $(".pverify").val();
        var result5 = result + result2 + result3 + result4 - val7;
        var result6 = result5 * 12;
        $("#result").val("$" + result);
        $("#result2").val("$" + result2);
        $("#result3").val("$" + result3);
        $("#result4").val("$" + result4);
        $("#result5").val("$" + result5);
        $("#result6").val("$" + result6);
  });
});

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

EDIT: This answer is correct for version 0.2.10. As @Alexander Vasilyev pointed out it doesn't work in version 0.2.14.

Another reason to use $state.params is when you need to extract query parameters like this:

$stateProvider.state('a', {
  url: 'path/:id/:anotherParam/?yetAnotherParam',
  controller: 'ACtrl',
});

module.controller('ACtrl', function($stateParams, $state) {
  $state.params; // has id, anotherParam, and yetAnotherParam
  $stateParams;  // has id and anotherParam
}

This works, as long as you remove the height attribute from the table.

<table id="content" border="0px" cellspacing="0px" cellpadding="0px">
  <tr><td height='9px' bgcolor="#990000">Upper</td></tr>
  <tr><td height='100px' bgcolor="#990099">Lower</td></tr>
</table>

Use below command to change computer hostname remotely , Require system reboot after change..

psexec.exe -h -e \\\IPADDRESS -u USERNAME -p PASSWORD netdom renamecomputer CurrentComputerName /newname:NewComputerName /force

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

Another possibility would be grouping, similar to how you might approach it in raw SQL:

from y in context.MyTable
group y.MyCounter by y.MyField into GrpByMyField
where GrpByMyField.Key == value
select GrpByMyField.Max()

The only thing is (testing again in LINQPad) switching to the VB LINQ flavor gives syntax errors on the grouping clause. I'm sure the conceptual equivalent is easy enough to find, I just don't know how to reflect it in VB.

The generated SQL would be something along the lines of:

SELECT [t1].[MaxValue]
FROM (
    SELECT MAX([t0].[MyCounter) AS [MaxValue], [t0].[MyField]
    FROM [MyTable] AS [t0]
    GROUP BY [t0].[MyField]
    ) AS [t1]
WHERE [t1].[MyField] = @p0

The nested SELECT looks icky, like the query execution would retrieve all rows then select the matching one from the retrieved set... the question is whether or not SQL Server optimizes the query into something comparable to applying the where clause to the inner SELECT. I'm looking into that now...

I'm not well-versed in interpreting execution plans in SQL Server, but it looks like when the WHERE clause is on the outer SELECT, the number of actual rows resulting in that step is all rows in the table, versus only the matching rows when the WHERE clause is on the inner SELECT. That said, it looks like only 1% cost is shifted to the following step when all rows are considered, and either way only one row ever comes back from the SQL Server so maybe it's not that big of a difference in the grand scheme of things.

This is the common issue to resolve this you have to check some point

1. Include Main Jquery Library
2. Check Cross-Browser Issue
3. Add Library on TOP of the jquery code
4. Check CDNs might be blocked.

As Yaron mentioned, there isn't any difference between where and filter.

filter is an overloaded method that takes a column or string argument. The performance is the same, regardless of the syntax you use.

We can use explain() to see that all the different filtering syntaxes generate the same Physical Plan. Suppose you have a dataset with person_name and person_country columns. All of the following code snippets will return the same Physical Plan below:

df.where("person_country = 'Cuba'").explain()
df.where($"person_country" === "Cuba").explain()
df.where('person_country === "Cuba").explain()
df.filter("person_country = 'Cuba'").explain()

These all return this Physical Plan:

== Physical Plan ==
*(1) Project [person_name#152, person_country#153]
+- *(1) Filter (isnotnull(person_country#153) && (person_country#153 = Cuba))
   +- *(1) FileScan csv [person_name#152,person_country#153] Batched: false, Format: CSV, Location: InMemoryFileIndex[file:/Users/matthewpowers/Documents/code/my_apps/mungingdata/spark2/src/test/re..., PartitionFilters: [], PushedFilters: [IsNotNull(person_country), EqualTo(person_country,Cuba)], ReadSchema: struct<person_name:string,person_country:string>

The syntax doesn't change how filters are executed under the hood, but the file format / database that a query is executed on does. Spark will execute the same query differently on Postgres (predicate pushdown filtering is supported), Parquet (column pruning), and CSV files. See here for more details.

I think there is some confusion about the difference between MVC and Web Api. In short, for MVC you can use a login form and create a session using cookies. For Web Api there is no session. That's why you want to use the token.

You do not need a login form. The Token endpoint is all you need. Like Win described you'll send the credentials to the token endpoint where it is handled.

Here's some client side C# code to get a token:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //string token = GetToken("https://localhost:<port>/", userName, password);

    static string GetToken(string url, string userName, string password) {
        var pairs = new List<KeyValuePair<string, string>>
                    {
                        new KeyValuePair<string, string>( "grant_type", "password" ), 
                        new KeyValuePair<string, string>( "username", userName ), 
                        new KeyValuePair<string, string> ( "Password", password )
                    };
        var content = new FormUrlEncodedContent(pairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            var response = client.PostAsync(url + "Token", content).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

In order to use the token add it to the header of the request:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //var result = CallApi("https://localhost:<port>/something", token);

    static string CallApi(string url, string token) {
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            if (!string.IsNullOrWhiteSpace(token)) {
                var t = JsonConvert.DeserializeObject<Token>(token);

                client.DefaultRequestHeaders.Clear();
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + t.access_token);
            }
            var response = client.GetAsync(url).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

Where Token is:

//using Newtonsoft.Json;

class Token
{
    public string access_token { get; set; }
    public string token_type { get; set; }
    public int expires_in { get; set; }
    public string userName { get; set; }
    [JsonProperty(".issued")]
    public string issued { get; set; }
    [JsonProperty(".expires")]
    public string expires { get; set; }
}

Now for the server side:

In Startup.Auth.cs

        var oAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider("self"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            // https
            AllowInsecureHttp = false
        };
        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(oAuthOptions);

And in ApplicationOAuthProvider.cs the code that actually grants or denies access:

//using Microsoft.AspNet.Identity.Owin;
//using Microsoft.Owin.Security;
//using Microsoft.Owin.Security.OAuth;
//using System;
//using System.Collections.Generic;
//using System.Security.Claims;
//using System.Threading.Tasks;

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;

    public ApplicationOAuthProvider(string publicClientId)
    {
        if (publicClientId == null)
            throw new ArgumentNullException("publicClientId");

        _publicClientId = publicClientId;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        var user = await userManager.FindAsync(context.UserName, context.Password);
        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        var propertyDictionary = new Dictionary<string, string> { { "userName", user.UserName } };
        var properties = new AuthenticationProperties(propertyDictionary);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        // Token is validated.
        context.Validated(ticket);
    }

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        foreach (KeyValuePair<string, string> property in context.Properties.Dictionary)
        {
            context.AdditionalResponseParameters.Add(property.Key, property.Value);
        }
        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        // Resource owner password credentials does not provide a client ID.
        if (context.ClientId == null)
            context.Validated();

        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
    {
        if (context.ClientId == _publicClientId)
        {
            var expectedRootUri = new Uri(context.Request.Uri, "/");

            if (expectedRootUri.AbsoluteUri == context.RedirectUri)
                context.Validated();
        }
        return Task.FromResult<object>(null);
    }

}

As you can see there is no controller involved in retrieving the token. In fact, you can remove all MVC references if you want a Web Api only. I have simplified the server side code to make it more readable. You can add code to upgrade the security.

Make sure you use SSL only. Implement the RequireHttpsAttribute to force this.

You can use the Authorize / AllowAnonymous attributes to secure your Web Api. Additionally you can add filters (like RequireHttpsAttribute) to make your Web Api more secure. I hope this helps.

I had this problem on my developent environment with Visual Studio.

What helped me was to Clean Solution in Visual Studio and then do a rebuild.

Well,

you can also use a third party library like Aspose.

This library has the benefit that it does not require Excel to be installed on your machine which would be ideal in your case.

Try this:

SELECT CONVERT(date, GETDATE())

I had the same issue, and found that it was the USB cable I was using that was causing the issue.
Changing the USB cable fixed the issue, and I could successfully install the app afterwards.

int numLines = 0;

Container( height: numLines < 7 ? 148 * WidgetsConstant.height : numLines * WidgetsConstant.height * 24, child: TextFormField( controller: _bodyText, maxLines: numLines < 7 ? 148 : numLines, keyboardType: TextInputType.multiline, textInputAction: TextInputAction.newline,
onChanged: (String value) { setState(() { numLines = '\n'.allMatches(value).length + 1; }); }, ), ),

In a case where you are using a custom cell type, say ArticleCell, you might get an error that says :

    Initializer for conditional binding must have Optional type, not 'ArticleCell'

You will get this error if your line of code looks something like this:

    if let cell = tableView.dequeReusableCell(withIdentifier: "ArticleCell",for indexPath: indexPath) as! ArticleCell 

You can fix this error by doing the following :

    if let cell = tableView.dequeReusableCell(withIdentifier: "ArticleCell",for indexPath: indexPath) as ArticleCell?

If you check the above, you will see that the latter is using optional casting for a cell of type ArticleCell.

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

Well, this can take long time to figure out. Few points to narrow it down:

• Identify what is killing the CPU. I recommend Process Explorer http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
• Identify what AppPool is causing this
• Fix your code

If this helps. Add the following property with value to your selector:

white-space: pre-wrap;

The current best way to do this is to use df.to_string() :

with open(writePath, 'a') as f:
    f.write(
        df.to_string(header = False, index = False)
    )

Will output the following

18 55 1 70   
18 55 2 67 
18 57 2 75     
18 58 1 35  
19 54 2 70 

This method also lets you easily choose which columns to print with the columns attribute, lets you keep the column, index labels if you wish, and has other attributes for spacing ect.

Apart from the <h:panelGroup> component (which comes as a bit of a surprise to me), you could use a <f:verbatim> tag with the escape parameter set to false to generate any mark-up you want. For example:

<f:verbatim escape="true">
    <div id="blah"></div>
</f:verbatim>

Bear in mind it's a little less elegant than the panelGroup solution, as you have to generate this for both the start and end tags if you want to wrap any of your JSF code with the div tag.

Alternatively, all the major UI Frameworks have a div component tag, or you could write your own.

''.join([a, b]) is better solution than +.

Because Code should be written in a way that does not disadvantage other implementations of Python (PyPy, Jython, IronPython, Cython, Psyco, and such)

form a += b or a = a + b is fragile even in CPython and isn't present at all in implementations that don't use refcounting (reference counting is a technique of storing the number of references, pointers, or handles to a resource such as an object, block of memory, disk space or other resource)

Drag and drop apk if the emulator is launched from Android Studio. If the emulator is started from command line, drag and drop doesn't work, but @Tarek K. Ajaj instructions (above) work.

Note: Installed app won't automatically appear on the home screen, it is in the apps container - the dotted grid icon. It can be dragged from there to the home screen.

An Instant is what it says: a specific instant in time - it does not have the notion of date and time (the time in New York and Tokyo is not the same at a given instant).

To print it as a date/time, you first need to decide which timezone to use. For example:

System.out.println(LocalDateTime.ofInstant(i, ZoneOffset.UTC));

This will print the date/time in iso format: 2015-06-02T10:15:02.325

If you want a different format you can use a formatter:

LocalDateTime datetime = LocalDateTime.ofInstant(i, ZoneOffset.UTC);
String formatted = DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss").format(datetime);
System.out.println(formatted);

This is for those who want to prevent users to enter decimal numbers

<input id="myInput" onkeyup="doSomething()" type="number" />

<script>
    function doSomething() {

        var intNum = $('#myInput').val();

        if (!Number.isInteger(intNum)) {
            intNum = Math.round(intNum);
        }

        console.log(intNum);
    }
</script>

You may be able to use the aggregate (or agg) function to concatenate the values. (Untested code)

df.groupby('A')['B'].agg(lambda col: ''.join(col))

Rather than using the ssh:// protocol prefix, you can continue using the conventional URL form for accessing git over SSH, with one small change. As a reminder, the conventional URL is:

git@host:path/to/repo.git

To specify an alternative port, put brackets around the user@host part, including the port:

[git@host:port]:path/to/repo.git

But if the port change is merely temporary, you can tell git to use a different SSH command instead of changing your repository’s remote URL:

export GIT_SSH_COMMAND='ssh -p port'
git clone git@host:path/to/repo.git # for instance

Try this:

var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG");

using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
{
    pictureBox1.Image = Bitmap.FromStream(stream);
}

Old-fashioned solution with appropriately named variables. This gives the code some spirit.

#include <cstdio>
int _(char*__){int ___=0;while(*__)___='_'==*__++?___+1:___;return ___;}int main(){char*__="_la_blba_bla__bla___";printf("The string \"%s\" contains %d _ characters\n",__,_(__));}

Edit: about 8 years later, looking at this answer I'm ashamed I did this (even though I justified it to myself as a snarky poke at a low-effort question). This is toxic and not OK. I'm not removing the post; I'm adding this apology to help shifting the atmosphere on StackOverflow. So OP: I apologize and I hope you got your homework right despite my trolling and that answers like mine did not discourage you from participating on the site.

Use the Mod % (modulus) operator

if ($x % 6 == 0) return 1;


function nearest_multiple_of_6($x) {
    if ($x % 6 == 0) return $x;    

    return (($x / 6) + 1) * 6;
}

I also had a similar problem and tried all of the above but nothing worked. And then I noticed that the image was loading fine for one file and not for another. The reason was: My image was named image.jpg and a page named about.html could not load it while login.html could. This was because image.jpg was below about and above login. So I guess login.html could refer to the image and about.html couldn't find it. I renamed about.html to zabout.html and re-renamed it back. Worked. Same may be the case for images enclosed in folders.

You can use hexdump's

import hexdump
hexdump.dump("Hello World", sep=":")

(append .lower() if you require lower-case). This works for both Python 2 & 3.

A couple of plain old foreach loops provides a clean solution:

foreach (XElement level1Element in XElement.Load("data.xml").Elements("level1"))
{
    result.AppendLine(level1Element.Attribute("name").Value);

    foreach (XElement level2Element in level1Element.Elements("level2"))
    {
        result.AppendLine("  " + level2Element.Attribute("name").Value);
    }
}

If you installed WAMP to c:\wamp then I believe your webserver root directory would be c:\wamp\www, however this might vary depending on version.

Yes, this is where you would put your site files to access them through a browser.

There is something wrong with the accepted answer, it sometimes (randomly) brings a clipped response from server. I do not know why, I did not investigate the faulty cause of the accepted answer because this code worked perfectly for me:

username='username'
password='password'

cmd='some useful command' 

ssh=paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(ip,port,username,password)

stdin,stdout,stderr=ssh.exec_command(cmd)
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)

stdin,stdout,stderr=ssh.exec_command('some really useful command')
outlines=stdout.readlines()

git commit -m "Merged master fixed conflict."

If the problem lies client side, this could be one of the causes of the error.

On clients TortoiseSVN saves client credentials under

Tortoise settings / saved data / authentication data.

I got the same error trying to commit my files, but my credentials were changed. Clearing this cache here will give you a popup on next commit attempt for re-entering your correct credentials.

I used a combination of all answers and this is what worked for me in the end:

Strange.

If it can't find explorer.exe, you should get an exception. If it can't find the folder, it should still open some folder (eg my Documents)

You say another copy of Explorer appears in the taskmanager, but you can't see it.

Is it possible that it is opening offscreen (ie another monitor)?

Or are you by any chance doing this in a non-interactive service?

I prefer to use an extension method to get the scripts object:

public static IJavaScriptExecutor Scripts(this IWebDriver driver)
{
    return (IJavaScriptExecutor)driver;
}

Used as this:

driver.Scripts().ExecuteScript("some script");

Add the following css class

.dropdown-menu {
    width: 300px !important;
    height: 400px !important;
}

Of course you can use what matches your need.

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

No, you can't.

But as a solid workaround, I would suggest to classify that first div as position:relative and use div::before to create an underlying element containing your image. Classified as position:absolute you can move it anywhere relative to your initial div.

Don't forget to add content to that new element. Here's some example:

div {
  position: relative;
}    

div::before {
  content: ""; /* empty but necessary */
  position: absolute;
  background: ...
}

Note: if you want it to be 'on top' of the parent div, use div::after instead.

The primary reason is when you don't want to run the code directly, but rather, want to inspect it. This can be for any number of reasons:

• Mapping the code to a different environment (ie. C# code to SQL in Entity Framework)
• Replacing parts of the code in runtime (dynamic programming or even plain DRY techniques)
• Code validation (very useful when emulating scripting or when doing analysis)
• Serialization - expressions can be serialized rather easily and safely, delegates can't
• Strongly-typed safety on things that aren't inherently strongly-typed, and exploiting compiler checks even though you're doing dynamic calls in runtime (ASP.NET MVC 5 with Razor is a nice example)

Use the below command to get the first row from a CSV file or any file formats.

head -1 FileName.csv

The easiest way:

// 0000FF
public static Color hex2Rgb(String colorStr) {
    return new Color(Integer.valueOf(colorStr, 16));
}
